VisionOS Unity - VR Mode - Control Render Resolution?

I'm using Unity 2022.3.56f, with Apple VisionOS App Mode set to 'Virtual Reality - Fully Immersive Space'.

It seems that the render resolution of my game in the Apple Vision Pro when I build is well below the native resolution of the AVP displays.

I can't see a setting in XR Plug-in Management Apple visionOS options, or in Quality settings, to increase the render resolutions. Is this possible?

I tried setting: UnityEngine.XR.XRSettings.eyeTextureResolutionScale= 2.0f For example, but this doesn't seem to do anything to the render resolution in the build.
